Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of DMC and its controlled subsidiaries. Only subsidiaries in which controlling interests are maintained are consolidated. All significant intercompany accounts, profits, and transactions have been eliminated in consolidation.
Income Taxes	Income Taxes The effective tax rate for each of the periods reported differs from the U.S. statutory rate due primarily to favorable foreign permanent differences, variation in contribution to consolidated pre-tax income from each jurisdiction for the respective periods and differences between the U.S. and foreign tax rates (which range from 20% to 35%) on earnings that have been permanently reinvested. We recognize deferred tax assets and liabilities for the expected future income tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. Any effects of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. The deferred income tax impact of tax credits are recognized as an immediate adjustment to income tax expense. We recognize deferred tax assets for the expected future effects of all deductible temporary differences to the extent we believe these assets will more likely than not be realized. We record a valuation allowance when, based on current circumstances, it is more likely than not that all or a portion of the deferred tax assets will not be realized. In making such determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, recent financial operations and their associated valuation allowances, if any. We recognize the tax benefits from uncertain tax positions only when it is more likely than not, based on the technical merits of the position; the tax position will be sustained upon examination, including the resolution of any related appeals or litigation. The tax benefits recognized in the consolidated financial statements from such a position are measured as the largest benefit that is more likely than not of being realized upon ultimate resolution. We recognize interest and penalties related to uncertain tax positions in operating expense.
Earnings Per Share	Earnings Per Share Unvested awards of share-based payments with rights to receive dividends or dividend equivalents, such as our restricted stock awards (“RSAs”), are considered participating securities for purposes of calculating earnings per share (“EPS”) and require the use of the two class method for calculating EPS. Under this method, a portion of earnings is allocated to these participating securities and therefore is excluded from the calculation of EPS allocated to common stock
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying value of cash and cash equivalents, trade accounts receivable and payable, accrued expenses and lines of credit approximate their fair value.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In July 2015, the FASB issued an accounting standards update to simplify the measurement of inventory and changes the measurement from lower of cost or market to lower of cost and net realizable value. This pronouncement is effective for reporting periods beginning after December 15, 2016. We currently are evaluating the potential impact the adoption of this standard will have on our financial statements. In April 2015, the FASB issued an accounting standards update to revise the presentation of debt issuance costs. Under this pronouncement, entities will present debt issuance costs in their balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the deferred debt issuance costs will continue to be included in interest expense. The pronouncement, which is to be applied retrospectively to all prior periods, is effective for fiscal years beginning after December 15, 2015, with early adoption permitted for financial statements that have not been previously issued. We currently are evaluating the potential impact the adoption of this standard will have on our financial statements. In June 2014, the FASB issued an accounting standards update to clarify the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The pronouncement is effective for reporting periods beginning after December 15, 2015. We currently are evaluating the potential impact the adoption of this standard will have on our financial statements. In May 2014, the FASB issued an accounting standards update to clarify the principles of recognizing revenue and to develop a common revenue standard and disclosure requirements for U.S. GAAP and IFRS. The pronouncement is effective for reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. We currently are evaluating the potential impact the adoption of this standard will have on our financial statements. In April 2014, the FASB issued an accounting standards update which changes the criteria for determining which disposal transactions can be presented as discontinued operations and modifies related disclosure requirements. The pronouncement is effective for reporting periods beginning after December 15, 2014, however, early adoption is permitted. Any future disposal transaction will be accounted for under this standard, but otherwise the adoption of this standard is not expected to have a significant impact on the Company's consolidated financial position or results of operations.
Inventories	Inventories are stated at the lower-of-cost (first-in, first-out) or market value. Cost elements included in inventory are material, labor, subcontract costs, and manufacturing overhead. As necessary, we record provisions and maintain reserves for excess, slow moving and obsolete inventory. To determine reserve amounts, we regularly review inventory quantities on hand and values, and compare them to estimates of future product demand, market conditions, production requirements and technological developments.
Customer Advances	On occasion, we require customers to make advance payments prior to the shipment of goods in order to help finance our inventory investment on large orders or to keep customers’ credit limits at acceptable levels.

Disclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.

- Definition

Disclosure of accounting policy for major classes of inventories, bases of stating inventories (for example, lower of cost or market), methods by which amounts are added and removed from inventory classes (for example, FIFO, LIFO, or average cost), loss recognition on impairment of inventories, and situations in which inventories are stated above cost. If inventory is carried at cost, this disclosure includes the nature of the cost elements included in inventory.
